4.9.1 External manual bypass
Auxiliary contact of the External Manual Bypass Switch on terminals MBY1-MBY2.
A normally open contact has to be connected to the UPS terminals (MBY1-MBY2);
when the contact is closed (see Manual Bypass procedure), the microprocessor will
acquire the status of the contact and shut down the inverter.
4.9.2 Diesel generator (DIESEL MODE)
Auxiliary contact of the Diesel Generator on terminal XD1-XD2.
A normally open contact has to be connected to XD1-XD2 terminals, when the
contact is closed (if diesel mode is enable) the microprocessor will acquire the status of
the contact and the rectifier will reduce the voltage to the value set.
4.9.3 Auxiliary battery contact
Aux battery contact on terminals BAC1-BAC2.
This auxiliary contact is necessary to indicate the position of the isolator (open-closed)
and the fuse status.
4.9.4 Remote emergency power off
Aux EPO contact on terminals EAC1-EAC2.
The voltage supply to the loads can be interrupted from a remote location by using
this contact (i.e. for safety requirements). A normally closed contact must be connected
to the UPS terminals (EAC1-EAC2); when this contact is open the static inverter and by-
pass switches are opened so that the output supply is interrupted.
